RAILWAY-CROSSING.

1f E Specication of Letters Patent.

Application filed February 26, 1908.

Patented NOV. 17', 1908.

Serial N0. 417,821.

To all whom it may concern:

Be it known that I, POWELL O. ADAMS, a citizen of the United States,residing at Cameron, county of Milam, and State of Texas, have inventedcertain new and useful Improvements in Railway Crossings, of which thefollowing is a specification.

My invention relates to crossings for railway tracks and particularly torailway crossings to be operated in connection with block signalsystems, and the object is to provide crossings which can be easilyoperated to prevent the pounding of the wheels against the rails and bywhich a firm and continuous track is provided for every engine, car, ortrain which may pass and which will be strong and durable.

Other objects and advantages will be fully explained in the followingdescription and Vthe invention will be more particularly pointed out inthe claims.

Reference is had to the accompanying drawings which form a part of thisapplication and specification.

Figure 1 is a plan view of the crossing, showing the connection for thepassage of a car or train in one direction. Fig. 2 is a plan view,showing one section of the means for making a continuous track by avariation in the actuating mechanism, one of the cylinders being shownin section. Fig. 3 is a vertical cross-section, taken either along theline a' m or y y of Fig. 1. Fig. l is a broken perspective view of oneof the stationary portions of the track. Fig. 5 is z. plan view, showingthe application of the invention for use in rail track frogs. F 6 is aplan view of another variation of the invention :appliedy to frogs.

Similar characters of reference are used to indicate the same partsthroughout the several views.

The meeting rails 1 and 2 are preferably made integral with each other.The sections 3, 4, 5, and 6 are stationary and may be made rigid andfirm in any suitable manner. The connections between the sections 3, 4,5, and 6 and the sections 1 an'd 2 are made by telescoping members. Eachconnection is made by a short move of element 7 and a long move ofelement S. The balls of the rail sections 3, 4, 5, and 6 connect withthe members 7 by means of tongue and groove joints. The main bodyportions of the sections may be of the usual form of rails havingextended base portions 9 which receive the members 7 and 8. The baseportion 9 has a flanged connection 10 which is engaged by the members 7and S which are slidable thereon. The members 7 and 8 are grooved toreceive the flanged connections 10. The stationary members and thetelescoping members between the tracks are provided with guards 3/1which brace the stationary and telescoping members and prevent thedisplacement of these members.

Means are provided for actuating the members 7 and S. Fig. 1 shows onemethod of moving these members. A single operating shaft 11 serves tooperate all the mem-- bers 7 and 8. The shaft 10 is provided with abevel gear wheel 11. Gear 11 rocks two shafts 12 and 13 by means ofbevel gear wheels 14 and 15 rigid on said shafts. The members 7 and Swhich make connection with sections 3 and. 5 are directly operated fromthe shafts 12 and 13. Rods 16 pivotally engage the crank portions ofshafts 12 and 13 and are connected to members 8 by I-bolts 17. In thismanner when the shafts 12 and 13 are rocked the members 8 may be moved adistance of two inches or whatever distance may be necessary. Ihemembers 7 and 8 have their meeting faces set at an angle to each otherso that car wheels passing over the same will run on a continuous tread,while passing over the lapped portions of the two members, and acontinuous tread is provided at the junctures of the members 7 with thesections 3, 4l, 5, and (3 by the tongue and groove connections of theballs of the respective elements. The members S have a longer travelthan the members 7. The short travel of the members 7 is accomplished bycollars 2O and 21 which are rigid on the push and pull rods 16 and theeyebolt 22. The rod 1o moves freely through .the bolts 22. The members Swill thus move one inch in either direction before the member 7 moves atall if the member 8 is arranged to move two inches. In any event themember 7 moves only one half as far as the member 8. Fig. 1 shows thetrack arranged for a train to pass over the sections 3 the push and pullrods 29 which are operatively connected on the crank-shafts 28 andpivotally connected to the members 8 by means of the connection 17. Thepush rods 29 are provided with rigid collars 20 and 21 and run throughthe eyebolts 22 and operate in the same manner as the rods 16 to actuatethe members 7 and 8. Turning the rod or shaft 10 in one direction willrock the shafts 12 and 13 to open the passage for a train over thetracks 3 and 5 and to close the passage to trains over the tracks 4 and6, as shown in Fig. 1. rlurning the shaft in the opposite direction willopen the members 7 and 8 :tor passage over the tracks 4 and 6 and closethe tracks 3 and 5. The members 8 will all be operated simultaneouslyand the members 7 will all be operated simultaneously.

Instead of the gearing shown in Fig. 1, the vmembers 7 and 8 may beoperated by compressed air. Fig. 2 illustrates the manner of usingcompressed air or steam for this purpose. The push rods 16 or 29 may beconnected with a piston rod 30 which operates in a cylinder 31. Thecylinders 31 are each provided with two connections 32 and 33 forreceiving compressed air from a supply source. Compressed air turned inthrough the connections 32 would disconnect the passage over track 3 andconnect the members for passage at right angles to track 3. Turningcompressed air in the vcylinders 31 through the pipes 33 would connectthe members for passage over the tracks 3 and disconnect for passage inthe other direction. This same method of shifting telescopic members maybe applied to frogs for railway tracks in the same manner as abovedescribed, as illustrated in Figs. 5 and 6.

Having fully described my inventionJ what I claim as new and desire tosecure by Letters Patent, is,-

1. A railway crossing comprising meeting rail members rigid with eachother at each corner ofthe crossing, continuous track forming membersbetween said meeting rail members consisting of stationary rail membersprovided with extended bases and movable rail members mounted on andslidable on said extended bases, and means for actuating said movablemembers.

2. A railway crossing comprising meeting rail members rigid with eachother at each corner of the crossing, continuous track forming membersbetween said meeting rail members consisting of stationary rail membershaving portions of their balls cut away and provided with extended basesand movable rail members having recesses in the balls thereof to receivethe reduced ball portions of said stationary members and mounted on andmovable on said extended bases, and means for actuating said movablerail members.
